To turn off the TP all you have to do is just press the FM button (or the AM button I guess). As you've probably discovered, pressing the TP button a second time doesn't switch it off, which is a ridiculous design flaw. Note that if you press the CD or Tape button, you will just activate that feature but traffic reports will still interrupt your listening pleasure so make sure you hit the FM button before going to CD if TP is on (assuming you don't want traffic reports).
